To all who m n may concern:

Be it known that l, JonN A. S'roxn, a eitizin'i oi the United States, residing at Chi cage. in. the count) ot Cook and State of Illinois. have invented certain new and useful Improvements in 'longue 'lrnel s for T ot' which the tollmving a l. tiration. My invention relates to tongue truelqs designed to h controlled by the operator in a manner whereby the path of movement of the harvester may be governed independent ot the line of draft; the object, of the in vention heing to provide a (levire strong and dnrahle in its (.'()llf-ti.ll(3tlt)ll. easy to lllillllplh late. and etlieient in operation. I attain these results by .tneans of the mechanism illustrated in the aecoin imnying drawing. in white Figure l is a side ele atiojn of a tongue trueh en'rhodying my invention; Fig. i a front elevation ot a part. o'l Fig. 1; Fig. 3 represents a detail drawing of the guiding means and an associated part of the draft mechanism; Fig. -l is a detail of the eontrolling lever tnerhaniant; l ig. 5 is a top plan view of a. part of Fig. l. and designed to illustrate the mode of operation ot a part of the truck mechanism; Fig. t' is a detached detail retn'esenting a partof the loel-1- ing mechanism forming a part of the trurk controlling means; Fig. 7 a sideeleration of a detail part of the looking detent larch-- anisin; Fig. 8 is an end elevation Oil the part shown in Fig. 7.

The same reference numerals designate similar parts throughout the several views. 1 represents a stub tongue, which ma he connected with a harvester or lilce inarhine in any convenient manner; 2 is a seat for the tnierator supported by the stuh tongue; 3 and 4t; represexit upper and lower journal boxes secured to the tin-ward end (it the stuh tongue; firepresents a vertiral spindle journaled in said boxes; (3 is a lrtlll' axle pivotally connected with the lower end ot' the vertieal spindle at T in a manner to have a limited Vihratile inoven'tent relative to the axis of the spindle. and S retn'esents truck wheels 'jonrnaled on opposite ends of said axle.

The parts comprising the ronneetion between the lower end of the spindle and the truck axle inelnd a. hraeltet 9. having av vertiealfsoelcet portion 10 adapted to receive the spindle, a clevis-like lower end adapted to their lower ends; to the. hent axle,

t ansversel'y arranged ha r it; seeured thereto.

and the rear end of a hainn'xer strap 17 ha ving its forward end secured to the torward end of the longitudinal bar. The frame members 18 have their forward end secured to opposite ends of the. traneveree bar and and it represents a segn'iental. raolc having i ward ends also SfClllft-(l to opposite e:- the transverse int; and its eurved slidahly er longitudii ha r and provided with teeth 2t upon its inner edge adapted to he engaged with a. sliding spring-plea ed detent 2l.ln1ving its inner end arranged in a bracket 22 secured to thelongitndinal har and overlap ping the segment. raelt. and its oppoeito end supported of, a lu'aolwti 2E :strured to the longittn'liinil har and provided with verti- (rally arranged ears Qt. hetwern \Yillt'll is pivotally mounted a hell crank lever having one of its arms engaging with the for ward end ot the detent and the other with the lower end of a rod 2! that; has its upper end connected with a hell erank lever 2? at thp upper end ot the vertieal spindle.

5 represents a part secured to the upper .itnd of the spindle and tn'ovided with a transversely arranged sleeve 33) adapted to rereive the hook end 3?) oi a hand lever ill. the hell rrani; lever 27 heing pivotally mounted upon an extended portion oil the hook l l. and ilfl represent, ear portions integral with the part 28 and adapted to to reive hetween them the hand lever. and 33 is a retaining pin operative to seeure the lever in position. the lever heing ]')rovided with a. hand piece 34 and thumb lever 35. the latter heing connected with the hell eraulc lever 27 hr means ot a rod ill.

37 reprtents a (trail; ttnigue, having soenred to its rear end a nieinher 35 provided with'ear portions 39 projecting rearward'ly and connected with a member 48 seenred to the forward end o l? the longitudinal bars to by means of a. pivot pin-42.1

lltl

Hooked to the under side of the draft 1 pivotally connected with the lower end of tongue is a rod 42, and slidably connected with the rod is an eye member L3, to which is secured the forward end of a lever 44 that is curved laterally at its rear end and provided with downwardly extending ear portions 45 that have openings therein to receive the pivot pin 41, whereby the rear end of the bar may be connected with the member 40.

When the lever is connected in the manner described the draft tongue is connected to the stub tongue by means of an angular frame, the latter including laterally and forwardly projecting bars 46, having their rear ends secured to the upper and lower sides of the stub tongue by means of a bolt 47, and at their forward ends provided with a coupling member 48 adapted to connect with the.

member 38 at the rear end of the draft tongue by means of the pivot pin 4:1 and 49 represents a brace member having its outer end secured to the bars 46 and its inner end to the stub tongue. 50 represents the eveners, that are 'pivotally connected with the forward ends of the bars 46by means of straps 51 and bolts 52. L

In the operation of the inechanism as described, the truck will, through its lever connection with the draft tongue, be guided directly thereby, or, when desirable, it may be turned either to the right or left of the line of draft independent of the movement of the draft tongue, by means of the hand lever and secured in any position of adjustment by means of the locking mechanism. 1
